The vtkLoadPythonWidgets.py looks in plenty of locations for the
vtkRenderingPythonTkWidgets.dll, including the tcl 'auto_path',
the default python path, and PYTHONPATH.

But I don't think that the tcl-level widget is the problem, or else the
exception that is generated would be a TclError stating that
vtkRenderingPythonTkWidgets.dll could not be found.  The stated error
was that the vtkLoadPythonWidgets module was missing, so my guess
is still that vtkLoadPythonWidgets.py is not being found for some
reason.
